Problem solving takes place not only in mathematics classes but also in real-world. For this reason, a problem and the structure of problem solving, and the enhancing of success in problem solving is a subject which has been studied by any educators. In this direction, the aim of this study is that the strategy used by students in Turkey when solving oral problems and their achievements of choosing operations when solving oral problems has been researched. In the research, the students have been asked three types of questions made up groups of 5. In the first category, S-problems (standard problems not requiring to determine any strategy but can be easily solved with only the applications of arithmetical operations), in the second category, AS-SA problems (problems that can be solved with the key word of additive operation despite to its being a subtractive operation, and containing the key word of subtractive operation despite to its being an additive operation), and in the third category P-problems (problematic problem) take place. It is seen that students did not have so much difficulty in S-problems, mistakes were made in determining operations for problem solving because of memorizing certain essential concepts, and the succession rate of students is very low in P-problems. The reasons of these mistakes as a summary are given below: $\cdot$ Because of memorizing some certain key concepts about operations mistakes have been done in choosing operations. $\cdot$ Not giving place to problems which has no solution and with incomplete information in mathematics. $\cdot$ Thinking of students that every problem has a solution since they don't encounter every type of problems in mathematics classes and course books.

Purpose: This research is to find the general and somewhat prevailing problems in quality circle papers. Many quality circles try to benchmark awarded papers even though they may have common problems. By pointing out popular problems in papers, many quality circles hopefully could be guided to the right direction in working out improvement actions. Methods: Many papers awarded in national quality circle conferences are deeply analyzed to figure out common problems. 69 recent papers are analyzed step by step and the most important and frequently occurring problems in each step are indicated. Results: Many prevailing problems are found in each step of QC stories. Especially finding themes, Grasping status quo, Cause analysis, Setting targets, Development of and Implementing counter attacks are the most common areas that have problems. Conclusion: Some problems are already too popular to be recognized as problems. In this paper those problems are logically criticized and thereby right directions for future quality circle activities are proposed.

This study was done to identify the degree of congruence between nurses and patients on patients' health problems. The purposes of this study were 1. To compare the health problems of parturient women as identified by interview and in the nursing record. 2. To compare the health problems of patients who have had gynecological surgery as identified by interview and in the nursing record. 3. To compare the health problems of chemotherapy patients as identified by interview and in the nursing record. The design of this study was a comparative descriptive design. The subjects were 205 Obstetric-Gynecologic patients. The tool for this study was an 11 item questionnaire, including one open ended question on the patient's problem during the past one day. Data was collected through interviews and an audit of the nursing records during the period from March 22, 1992 to April 29, 1992. Data was analyzed using by frequencies and percentiles. The result of this study were summarized as follows : Pain was the most prevalent complaint for parturient women by interview(60.3% ) and from the nursing records(83.2%). There was no record in the nursing records about the complaints of lack of information and emotional problems even though there were complaints of communication problems (17.6%) and of emotional problems(3.5%) identified in the interviews but there were more records of cardiopulmonary problems in nurses record(9.1%) than the patient interviews (3.3%). In the nursing records 25.9% of the identified records identified pain problems compared with 23.3% in the interviews. In the nursing records, 22.3% of the records identified nutrition problem as compared with 18.2% in the interview. There were only a very few emotional problem identified in the nursing records (3.7%) as compared to 18.2% in the interviews. There were no comments about communication problems in the nursing records but 5.2% of the subjects mentioned of communication problems in the patient interview. There were problems in five categories for the parturient women ; comfort, communication, activity and rest, elimination, emotions, and there were problems in ten categories for the surgery patients : comfort, elimination, communication, emotions, nutrition, cardiopulmonary, thermoregulation, physical integrity, host defense and activity /rest. There were also problems in the same ten categories for chemotherapy Patients. On the other hand, in the nursing records, only comfort activity /rest, and elimination problems were identified for the parturient women, there were only seven categories of problems : comfort, elimination, cardiopulmonary, activity /rest, and nutrition for the gynecology surgical patients, and for the chemotherapy Patients, comfort, nutrition, physical integrity, cardiopulmonary, activity /rest, thermoregulation, emotion and elimination were the categories identified, and no communication problems were identified. It was found that there was low congruence between the patients' problems as identified through patient interview and as recorded in the nursing records. Therefore it can be concluded that the main content of the nursing records is the physical problems of the patients and this is not in congruence with the patients' reported problems in the emotional and communication domain.

This study examined emotion regulation, parental support, supervision, psychological control and marital conflict and victimization by peer harassment that affect children’s behavioral problems. The sample consisted of 412 fifth and sixth grade children. Statistics and methods used for the data analysis were percentage, frequency, Cronbach’s alpha, Factor analysis, t-test, Pearson’s correlation, and multiple Regression. Several major results were found from the analysis. First, girls had more internalized behavioral problems than boys. No sex difference was found in externalized behavioral problems. Second, boys’ and girls’ internalized and externalized behavioral problems showed positive correlations with maladaptive emotion regulation and parental psychological control. Boys’ and girls’ internalized behavioral problems and girls’ externalized behavioral problems showed negative correlations with parental support, but positive correlations with parentral marital conflict and victimization by peer harassment. Girls’ internalized and externalized behavioral problems showed negative correlations with parental supervision. Third, maladaptive emotion regulation was the most important variable predicting boys’ and girls’ externalized behavioral problems and girls’ internalized behavioral problems. Victimization by peer harassment was the most important variable predicting boys’ internalized behavioral problems.

While Internet-based distance learning has proliferated, its educational effectiveness remains controversial. As such, investigation into the problems of Internet-based distance learning is important and fundamental for an assessment of its educational effectiveness. In this study, problems of Internet-based distance learning are grouped into four categories, environmental problems, student problems, course design problems and operational problems. Based on survey data from 606 distance learning participants, perceptional and relative seriousness of problems are analysed. The results indicate that perceptional seriousness of all the problems is not statistically important. However, the findings indicate that the relative seriousness of self willingness among student problems and cheating within operational problems is most remarkable. In contrast, the relative seriousness of traditionally recognized problems such as H/W availability and network speed among environmental problems is least remarkable. An analysis of demographic differences such as sex, employment and age in terms of seriousness of problem is also performed. The results reveal the existence of statistically significant differences according to sex, employment, and age difference with regard to seriousness of problems.

This study explored relationships between internal locus of control, ego-resilience, and behavior problems including effects of ego-resilience as mediating variables of behavior problems in 135 institutionalized children. Instruments were the Locus of Control (Min, 1999) and Ego-resilience (Yoon et al. 2001) scales and Korea-Child Behavior Checklist (Oh et al., 1997). Locus of control was administered to the children; ego-resilience and behavior problems were rated by teachers. Findings were that (1) internal locus of control related positively to ego-resilience and negatively to behavior problems; ego-resilience related negatively to behavior problems. (2) Effects of internal locus of control on behavior problems were mediated by ego-resilience; ego-resilience sub-factors of peer relationships and comprehension ability mediated relationships between internal locus of control and behavior problems.

This study investigated the mediating and moderating effects of teacher preference on the relationship between behavior problems and peer victimization. The subjects were 520 children in the fifth and sixth grades. Children completed peer nominations that assessed peer victimization. Teachers rated children's internalizing, externalizing problems and teacher preference. The full mediating effect of teacher preference was found in externalizing problems and the partial mediating effect was found in internalizing problems. Moreover, the moderating effect of teacher preference was found only in internalizing problems, which suggests that high teacher preference protects internalizing problems from peer victimization.

Scientificc inquiry has been a major goal and a vehicle to teach science in schools since Curriculum Reform Era. Based upon the Laudanian philosophy of science, scientific inquiry problems were classified and their characteristics were identified. Science inquiry problems could be classified as empirical and conceptual problems. Empirical problems consist of unsolved, solved, and anomalous problems. Internal and external conceptual problems are included in conceptual problems. Effective teaching methods for solving empirical and conceptual science problems are discussed. The implications of Laudanian philosophy of science for science teaching were also discussed.

Using a sample size of 643 college students, this study examined the level of financial stress and financial problems of college students and investigated the factors related to stresses and problems. A majority of the students had experienced financial stress that interfered their study. Among the financial problems, spending problems were the most problematic. The results of the study indicated that financial knowledge and practice were important determinants of students' financial stress and problems. Some of the demographic variables, such as family income, were also important in predicting the students' spending problems. It was suggested that good financial practices of expenditure and maintenance of those practices were important to reduce or prevent financial problems and distress. Financial educators and parents should provide their support in helping students handle their finances responsively.
